Borga 2 & 3 layer membrane

BORGA Roof Membrane is the high quality layer for using as a indispensable layer in roofs constructions.

It is multilayer polypropylene fabric. Among the roofer materials it is to classify as a highly let in initial covering film. It means that it is placed directly over the thermal insulations, without the need of leaving ventilation crack.

Borga Roof Membrane

BORGA Roof Membrane film controls steam condensing processes, and condenses accumulating, because it is constructed that, it does not lets in water, but it absolutely does lets in the steam. So, the water will make no humidity in rafter framing, and in insulation, but will flow down on the film surface. From the opposite direction the steam will freely get out thru the film, without accumulating in thermal insulation. That is why, the high let in of steam, is so important parameter.

Borga Roof Membrane is:

Extremely light
Stretching and tearing durable
Waterproof
Highly let in
Fast and easy in instalment
Recyclable

Borga Roof Membrane Reinforced

Our long-term practices of paving initial covering films indicates that, in these places of roof, were the films are opened to damages; one should put stronger kinds of films.

Undoubtedly, no matter of the kind of coating, these places are: valleys, and eaves.

Valleys a greater number of more difficult actions than other parts of the roof, it goes along with the higher risk of damaging the membrane. These places are extremely loaded at extreme weather conditions. Because of the same reasons, eaves require stronger membranes.

Roof ridges, and roof hips are in a basic standard version covered twice by applying a coat of two roof slopes of membrane layer. Instead of this solution one may (but not necessarily) put on roof ridge, and roof hip another layers of a regular membrane.

Reinforced films one also ought to use at all roof's area, if its roof slopes are slanted at low angles.
